Acanthamoeba Keratitis Overview

Acanthamoeba keratitis is a rare but serious corneal infection primarily affecting contact lens wearers, though it can also occur in individuals who experience corneal trauma without lens use. This infection is caused by the Acanthamoeba genus, a ubiquitous unicellular protozoan parasite found in diverse environments, including soil, water, and air. Acanthamoeba keratitis poses a significant threat to vision, as it can lead to severe corneal ulceration, loss of visual acuity, and potentially blindness if not diagnosed and treated promptly.

The disease is associated with various genotypes of Acanthamoeba, with genotype T4 being the most commonly implicated. Symptoms of Acanthamoeba keratitis typically include redness and inflammation of the eye, photophobia (sensitivity to light), blurred vision, and ocular pain. These symptoms can progress rapidly, emphasizing the need for early detection and intervention to prevent complications. As awareness of Acanthamoeba keratitis grows, understanding its risk factors, clinical presentation, and management strategies remains crucial for preserving visual health in at-risk populations.

Acanthamoeba Keratitis Diagnosis and Treatment Algorithm

Acanthamoeba keratitis presents significant diagnostic challenges, often being misdiagnosed due to its clinical resemblance to other keratitis forms, such as herpetic and bacterial keratitis. Early and accurate diagnosis is imperative for effective management, utilizing several diagnostic modalities. Corneal scrape or biopsy can provide direct evidence of the organism, while polymerase chain reaction (PCR) techniques enhance sensitivity and specificity in identifying Acanthamoeba DNA. Impression cytology and in vivo confocal microscopy serve as valuable adjuncts, allowing for real-time visualization of the corneal epithelium and detection of the parasite.

The treatment landscape for Acanthamoeba keratitis primarily revolves around the use of topical anti-amoebic agents, which are often employed in combination to enhance efficacy against both the trophozoite and cyst forms of the pathogen. The standard treatment regimen necessitates aggressive topical therapy, typically involving medications such as chlorhexidine and voriconazole, tailored to the severity of the infection. In advanced cases, where corneal damage is extensive, corneal transplantation may become necessary to restore vision. Thus, preventing Acanthamoeba keratitis through avoidance of risk factors, coupled with prompt diagnosis and treatment, remains pivotal in mitigating the impact of this sight-threatening infection.

SIFI’s AKANTIOR (polihexanide) emerges as the only approved therapy specifically for Acanthamoeba keratitis, addressing a critical unmet need in the treatment of this rare condition. Its approval not only positions SIFI as a leader in the market but also sets a potential new standard of care, paving the way for further global expansion and the introduction of additional therapeutic options.

Key Findings

According to the United States Centers for Disease Control and Prevention (CDC), it was estimated that around 85% of Acanthamoeba keratitis cases occur in contact lens users in the US.

In the US, 95% of the patients were contact lens wearers, of whom 74% wore soft contact lenses. The number of cases increased from 2009 to 2015. This resulted in an estimated incidence of one in 21,000 for soft contact lens wearers in 2015.

The incidence of Acanthamoeba keratitis was found to be approximately 1–2 new cases per million contact lens wearers annually in the US; approximately 17% of the US adult population wears contact lenses.

In a systemic review, it was found that the ratio of eyes with Acanthamoeba keratitis in relationship to the entire population in Italy, was estimated at 2.34 eyes per million people.

A prospective survey conducted in the UK reported an overall incidence of 2.35 cases per million. Contact lens wearers accounted for 87%, in whom the Acanthamoeba keratitis incidence was 26.94 per million.

It was found that in Europe, the UK has the highest incidence of Acanthamoeba keratitis, and its growth is associated with the increase in the use of contact lenses since the 1990’s. Thus, Acanthamoeba keratitis remains a significant concern for contact lens wearers accounting for approximately 87% incidence.

According to various studies which estimated the genotype of Acanthamoeba species in Acanthamoeba keratitis, the isolates were predominantly genotype T4 with nearly 80%, while the genotype T3 accounted for nearly 13%.

Acanthamoeba Keratitis Market Outlook

The treatment of Acanthamoeba keratitis is challenging due to the cyst form’s resilience, requiring a multifaceted approach. Current regimens typically include topical cationic antiseptics, such as polyhexamethylene biguanide (0.02%) or chlorhexidine (0.02%), often combined with diamidines like propamidine (0.1%) or hexamidine (0.1%). Treatment duration ranges from six months to a year, with pain management through topical cycloplegic solutions and oral non-steroidal medications.

Evolving treatment strategies have shown success with various combinations of antibiotics, antivirals, antifungals, and antiparasitic drugs, although many topical therapies are not available in the US. Therapeutic regimens may include diamidines, biguanides, and antibiotics like neomycin-polymyxin B-gramicidin, which eliminate bacteria serving as a food source for Acanthamoeba. Antifungals such as voriconazole and miconazole may also be used.

Close monitoring is essential, often requiring daily follow-ups until clinical improvement is observed. Given the potential for recurrence and the cysts’ resistance to treatment, tapering therapy should be gradual. The use of corticosteroids is controversial due to the risk of impairing the immune response. Surgical interventions, including penetrating keratoplasty, may be necessary for corneal perforation or significant scarring, but if active infection persists, medical therapy must resume. No single chemotherapeutic agent has proven universally effective against Acanthamoeba keratitis, reflecting the diverse virulence traits of Acanthamoeba isolates.

With ongoing research and continued dedication, the future holds hope for even more effective treatments and, ultimately, a cure for this challenging condition. According to DelveInsight, the Acanthamoeba Keratitis market in the 7MM is expected to change significantly during the study period 2020–2034.
